23 Nov What is Polymer Concrete: Types, Uses and Advantages
Ever seen some cracks or wear in a building that once looked brand new? This happens because of constant water exposure, high traffic, or harsh weather conditions.
Over time, regular concrete loses its strength and durability. In such situations, polymer concrete can be the best option.
Let’s talk about polymer concrete in detail.
What is polymer concrete?
Unlike traditional concrete, Polymer Concrete uses epoxy, polyester, or acrylic resin as binders. These resins make a dense, strong matrix, improving durability and load-bearing capacity. And that’s what makes it ideal for demanding applications.
Properties of Polymer Concrete
Now that we know about polymer concrete, let’s explore its properties one by one. Here are some of them:
High Tensile Strength
Polymer concrete has high strength. It can resist salts, acids, and alkalis due to its low water absorption and strong adhesion. It also cures faster in high-temperature conditions, making it efficient for heavy-duty applications.
Low Thermal Conductivity
Polymer concrete has lower thermal conductivity (0.15 to 0.48 W/m*K) compared to traditional concrete. This property makes it less prone to temperature-induced expansion and contraction. This helps structures stay stable in areas with changing temperatures.
Less Porosity
The polymer films seal the micropores on the surface and around the gravel and crushed stone. Consequently, this reduces its porosity.
High Abrasion Resistance
It’s resistant to wear because its core structure protects it from damage caused by heavy use. This makes it ideal for industrial floors and high-traffic areas.
Lightweight
Polymer concrete is lighter than traditional concrete. And that’s why it is easier to handle and transport. Because of this property, it reduces construction costs and time.
Applications of Polymer Concrete
Polymer concrete is used in applications where durability is important. Let us look at these applications one by one.
Bridges and Road Construction
PC (Polymer concrete) is also used in the construction and repair of bridges. It is highly resistant to de-icing salts and severe weather. Also, it provides chemical resistance against heavy loads and spills on the surface.
Industrial Flooring
Industrial floors are vulnerable to foot traffic for a longer period. Therefore, it is used in industrial flooring. However, it is just not an industrial application. Industrial flooring in factories and chemical plants gives the advantage of abrasion resistance. Plus, it has the ability to accommodate machinery like tanks and sewage systems.
Architectural and Aesthetic
This type of concrete can also be applied in the field of architecture. It is used to manufacture prefabricated products, such as countertops and ornate structures. This way, concrete can achieve intricate and delicate, smooth finishing.
Marine and Coastal Infrastructure
You can use polymer concrete in marine infrastructure like docks, piers, and seawalls. Wondering why it is a perfect material there? All thanks to its resistance to harsh conditions like tides and saltwater. As per experts, polymer concrete can even reduce the need for frequent repairs in marine environments.
Electrical and Telecommunications
It can be used to construct electrical and telecommunications infrastructure. Cable trenches and ducts are among the best examples of this. Polymer concrete resists chemicals and has high strength. This makes it the perfect option for protecting electrical equipment.
Parking Structures
It is used to construct garages and ramps. Due to its resistance to de-icing salts, it can withstand heavy loads from vehicles. It ensures long-lasting performance in areas subjected to constant traffic and harsh weather.
Types of Polymer Concrete
Since polymer concrete is more about versatility, there are a number of types of concrete. Each type has a slightly different composition. Here are a few common types:
Polymer Impregnated Concrete (PIC):
This kind of concrete is precast and conventional, and it is then cured in an oven or by dielectric heating. The air in the open cell is then drawn out using a vacuum. Afterward, a low-viscosity monomer is spread throughout the cell. Then, it is polymerized through the application of heat or radiation.
Polymer Cement Concrete (PCC)
PCC is a mix of traditional concrete and polymer resins. Instead of using water as the binder, the polymer binds everything together. This makes it tougher and has higher chemical resistance than regular concrete. It’s perfect for areas where the concrete will face heavy wear and tear.
Advantages and Disadvantages of Polymer Concrete
Here are some pros and cons of polymer concrete in heavy-weight applications. Let us talk about them:
| Feature | Pros | Cons |
| Strength | High tensile, flexural, and compressive strength | It can be less durable in extreme heat. |
| Durability | Resistant to chemical attack and freezing/thawing cycles | It may have lower long-term durability compared to traditional concrete. |
| Curing | Rapid curing at room temperature | Requires specific curing conditions for optimal performance |
| Adhesion | Good adhesion to various surfaces | It may have weaker bond strength in certain applications. |
| Permeability | Low water permeability | May be more susceptible to certain types of chemical attack |
| Weight | Polymer concrete is lightweight | It may have a lower load-bearing capacity in some cases |
| Environmental Impact | It may have a higher environmental impact during production. | It can be recycled and reused. |
| Workability | It is easier to mold into intricate shapes and designs | It requires careful handling and may be more sensitive to mix ratios. |
| Cost | It is more expensive than traditional concrete due to the cost of polymers | Long-term savings from reduced maintenance and quicker curing can offset initial costs. |
| Thermal Conductivity | Low thermal conductivity, reducing temperature-induced expansion and contraction | It may not be suitable for high-heat environments where extreme temperature fluctuations occur. |
| Surface Finish | It can achieve a smooth and aesthetic surface finish for decorative applications. | In some cases, it may need surface treatments for optimal appearance. |
Conclusion
Polymer concrete is perfect for heavy-duty applications such as roads and industrial flooring. Though costly, its pros outweigh its cons, making it a worthwhile investment. However, while deciding on the right type of polymer, always asses your requirements or consult an expert.
